Answer:
1st Option
Step-by-step explanation:
Average rate of change formula: 
Simply plug in 8 as a and 6 as b.
Answer:
A.
Step-by-step explanation:
Δy /Δx = (y2 - y1)/(x2 - x1) = [g(x2) - g(x1)]/(x2 - x1)
[g(x2) - g(x1)]/(x2 - x1) =[g(8) - g(6)]/(8 - 6) =![\frac{[-8^{2}-4(8)]-[-6^{2}-4(6)]}{8-6}](https://tex.z-dn.net/?f=%5Cfrac%7B%5B-8%5E%7B2%7D-4%288%29%5D-%5B-6%5E%7B2%7D-4%286%29%5D%7D%7B8-6%7D)

Answer:
m = -4.33333 or -4 and 1/3
Step-by-step explanation:
gradient = (difference in y)/(difference in X)
m = (-1-12)/(8-5)
m = -13/3
m = -4.3333333

Answer:
(7, 0).
Step-by-step explanation:
We have y = 3(x - 7)
y = 3x - 21
Point-slope form is
y - y1 = 3(x - x1)
y - y1 = 3x - 3x1
Comparing this to the equation y = 4x - 21 we see that y1 = 0 and x1 = 7.
